Triple Layer Fudgy Mint Oreo Brownie Ingredients
For the Brownie Base
- Baking Chocolate – Major source of chocolate flavor; substitute with high-quality dark chocolate if desired.
- Unsalted Butter – Adds rich moisture; feel free to use margarine as an alternative.
- Granulated Sugar – Sweetens and balances flavors, but brown sugar can deepen the flavor profile.
- Eggs – Essential for structure and binding; consider flax eggs for a vegan option.
- Vanilla Extract – Boosts overall flavor; omit or reduce for a simpler taste.
- All-Purpose Flour – Provides the necessary structure; opt for gluten-free flour for a gluten-free version.
- Cool Mint Oreo Cookies – Adds unique crunch and mint flavor; regular Oreos can be used, but they lack the minty essence.
For the Mint Filling
- Marshmallow Fluff – Introduces sweetness and a chewy texture; homemade marshmallow makes a great substitute.
- Mint Extract – Infuses a bold mint flavor; use sparingly to prevent overpowering the brownie.
- Green Food Coloring – Enhances visual appeal; feel free to omit for a non-themed version.
For the Frosting
- Powdered Sugar – Provides sweetness for the frosting; reducing the amount yields a less sweet treat.
- White Chocolate Chips – Adds luxurious sweetness; can be replaced with semi-sweet chocolate or omitted.
- Milk – Adjusts frosting consistency; dairy-free alternatives work beautifully too.
These Triple Layer Fudgy Mint Oreo Brownies are a celebration of flavor and texture that your taste buds will adore!

Triple Layer Fudgy Mint Oreo Brownies Recipe FAQs
What type of chocolate should I use for the brownie base?
Absolutely! The brownies shine with baking chocolate, which provides rich chocolate depth. If you don’t have baking chocolate on hand, feel free to substitute it with high-quality dark chocolate for a similar flavor.
How should I store these brownies to keep them fresh?
Very simple! Store your Triple Layer Fudgy Mint Oreo Brownies tightly covered in the fridge for up to 10 days. This keeps them moist and maintains that lovely fudgy texture while allowing the mint flavor to develop further.
Can I freeze the brownies for later enjoyment?
Absolutely! To freeze, wrap the brownies tightly in plastic wrap, then place them in an airtight container or freezer bag. They can be stored this way for up to 6 months. When you’re ready to indulge again, simply thaw them in the fridge overnight before savoring.
What if my brownies are too dry?
If your brownies turn out dry, fear not! This often happens if they’ve been overbaked. To prevent this, stick to the recommended baking time (23-25 minutes). Always poke a toothpick in the center—look for moist crumbs rather than a clean pull. If they do come out dry, consider serving them warm with a scoop of ice cream to moisten them up!
Are these brownies suitable for those with allergies?
Considerate baking is key! These brownies contain eggs, dairy, and gluten, so if you’re making them for someone with allergies, substitute flax eggs for the eggs, use dairy-free milk, and switch to gluten-free flour. This way, everyone can enjoy a delicious treat!
Can I add more mint extract for a stronger flavor?
It’s tempting to ramp up the flavor, but I recommend sticking to the specified amount in the recipe. Adding more can overpower the dish and lead to an unbalanced taste. Trust the balance, and you’ll find the mint perfectly complements the chocolate!
